Title: Improvements in or relating to pressure regulators
IPC: F02D1/00
Filed: 1954-08-09
Abstract: 760,282. Valves. CUMMINS ENGINE CO., Inc. Aug. 9, 1954 [Oct. 13, 1953], No. 23069/54. Class 135. In a valve for regulating the pressure in, and by-passing fuel from, a fuel line supplying a plurality of fuel injectors, a tubular valve member 23 slidable in a body member 14 held in a casing 10 by members 20, 21 and urged by a spring 25 to close radial ports 30 houses a plug member 34 made from material having a greater coefficient of linear expansion than that from which the valve member 23 is made so that on increase in temperature of the fuel the resulting increase in flow consequent upon decreased viscosity is compensated by corresponding increased throttling of the ports 30. Fuel under pump pressure enters the casing at 11 and acts on the valve member 23 to urge it to the right against its spring 25 to regulate flow through the ports 30. Radial ports 33 by-pass the whole of the pump output when the engine is run at maximum speed and the speed governed throttle valve is closed. The plug 34 may be made of metal but preferably is made of a moulded plastic material. Shims 41 are placed under the head of the plug to determine its initial setting. To suit particular engine requirements further ports may be formed in the tubular valve member 23, e.g. radial ports spaced between the ports 30, 33 or flats formed on the outer periphery of the valve member which communicate with the inlet 11 and stop short of the ports 30 by varying amounts.

Abstract: 162,587. Das, P. Aug. 5, 1920. Lighting systems. -In an emergency lighting system for use in theatres &c. the bipolar switch 4, which controls the emergency lighting and relay circuits, has three positions, the second position serving to show whether the emergency circuit' is in order. In the first position, as shown, both circuits are open. In the second position, the righthand switch arm bears on a dead contact 14 whilst the left arm completes at the contact 15 the circuit of the battery 11 through the armature 8 of the relay 5 and the emergency lamp 12, to show if this lamp is effective. In the third position, the arms are on the contacts 17, 16, in the circuits of the relay 5 and the lamp 12 respectively. In this position, the relay is energized and, by attracting its armature, holds the emergency circuit open so long as the main installation is in effective use. The relay circuit includes one or more indicating-lamps 7.

Title: Four-Port Reversing Valve for Fluid Flow.
IPC: F16K11/07
Filed: 1967-05-18
Abstract: 1,154,689. Valves. DANFOSS A.S. 18 May, 1967 [7 June, 1966], No. 23196/67. Heading F2V. A reversing valve has a by-pass which incorporates a throttle whose resistance increases progressively as the reverse flow control is moved from its neutral position in which flow to and from the load is blocked. The valve housing has parts 19-22 which are connected to opposite sides of an hydraulic motor, a pump and a reservoir (Fig. 1, not shown), and which are interconnected by circumferential grooves and parts in a stationary member 24 and a rotary member 34 in such a way that rotation of member 34 reverses the flow of fluid to the motor. When member 34 is in its neutral position bores 31, 40 in members 34 and 24 respectively are fully aligned and form a fluid by-pass which closes progressively as fluid is directed to the motor by movement of member 34. Ports 54, 55 co-operate with ports 47, 48 (Fig. 6, not shown) to constitute further throttles, in series with throttle 31, 40, which serve to progressively throttle the bypass as piston 50 moves to the left in response to an increase in the pressure drop across ports 54, 55. In the event of excess pressure occurring in the valve, relief valve 58 opens.

Abstract: 616,006. Air heaters. SEGRAVE, C. R., WILLIAMS, T. B. GLYNNE-, and BARKER, H. H. Aug. 8, 1946, No. 23484. [Classes 64(i) and 64(iii)] An air heater for aircraft comprises a combustion chamber 1 for oil or gas surrounded by an outer chamber 9 spaced from the combustion chamber, both chambers being mounted in a casing 17 through which air flows while burning gases are caused to pass through the combustion chamber and through the outer chamber 9. A burner head 4 contains a sparking plug 5 and fuel-injecting jets 21 and communicates with the combustion chamber through ports 7. The hot gases leave the chamber 1 through radial ducts 10 and after passing through the annular chamber 9 enter an exhaust flue 11. A further outer chamber 13 surrounds the chamber 9 and carries the exhaust gases from an internal combustion engine which operates both a fan for blowing air through the apparatus and a fuel-pump. The outermost chamber 13 also discharges into the flue 11. The chambers 1, 9, and 13 are spaced apart from one another to allow the maximum heat transference. A flue 18, normally closed by a hinged flap 22, acts as a safety valve if the pressure in the combustion chamber is excessive.

Abstract: 1,011,305. Aerials. SIEMENS & HALSKE A.G. Nov. 23, 1962 [Nov. 23, 1961], No. 23632/65. Divided out of 1,011,303. Heading H4A. Means are described for modifying a known aerial array, Fig. 1, comprising four half-wave dipole assemblies 2 and 3 (the other two not being shown), fed with signals from a common source via individual feeders such that at a certain frequency the phase of the energy reaching the dipole assemblies advances by 90 degrees from one assembly to the next, whereby the aerial can operate over a frequency range of 0À85 to 1À15 fm, where fm is the geometric mean frequency, without the minimum radiated energy in the horizontal plane falling below half the maximum value. In the arrangement of Fig. 3 dipole assembly 75 is fed with a feed line #m/4 shorter than that feeding assembly   74, dipole assembly 76 is fed with a feed line the same length as that feeding assembly 74, but with the addition of a phase reversing unit, and dipole assembly 77 is fed with a feed line the same length as that feeding assembly 75, but with the addition of a phase reversing unit. The dipole assemblies comprise shortened full-wave dipoles with a fineness ratio of 15, and spaced a distance 0À28 #m in front of their associated reflectors. Each assembly is shifted along their respective tower side such that along a diagonal direction H, Fig. 2, the radiation centre 67 of one assembly leads the radiation centre 66 of the adjacent assembly by a distance d = 0À77-,#m/4 rather than the normal #m/4 distances.

Abstract: 885,235. Pulse-generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 24, 1958 [July 26, 1957], No. 23760/57. Class 40(6). In a pulse generator of the type in which a pulse forming network- PFN is charged from a D.C. supply and discharged via a switching device such as T, a protective circuit is provided so that if the voltage of the PFN becomes reversed, the normally conductive valve V1 becomes cut off, actuating a flip-flop which cuts off the trigger pulses to the switching tube T by closing a gate for a predetermined period. In the circuit shown, the pulse forming network PFN is charged via an inductor H and a rectifier D and discharged via a load L when a thyratron or ignatron T is triggered. In the event of a breakdown occurring across the load L the PFN will re-charge negatively so that the gate will be closed for a predetermined period. Component R2 may be a resistor, a voltage sensitive resistor or a neon tube. Excess energy in the PFN may be dissipated by a resistor R5 which may be alternatively connected across the switching tube T, across both rectifier D and inductor H, or across the PFN. The potential divider R1, R2 feeding the grid of V1 may alternatively be fed from the cathode of rectifier D. Fig. 3, not shown, relates to a cathode-coupled flip-flop suitable for use with the invention.
